Abstract: 1,219,852. Thioamides. BADISCHE ANILIN- & SODA-FABRIK A.G. 14 March, 1968 [18 March, 1967], No. 12325/68. Heading C2C. N-substituted thioamides are prepared by reacting a haloalkane having at least one terminal halomethyl group with S and a primary or secondary amine, the S being used in about the stoichiometric amount per halomethyl group. The process may involve a haloalkane having more than one terminal halomethyl group and a monoamine or a haloalkane having one terminal halomethyl group and a polyamine. An acid binding agent such as an amine, amide and other organic and inorganic bases may be present. In the examples cyclohexylamine, di-n-butylamine and piperidine are converted to (a) N-cyclohexylthioformamide; (b) N,N-dibutylthioformamide; and (c) thioacetylpiperidine respectively using methylene chloride in (a) and (b), and 1,1-dichloroethane in (c).

Abstract: 1,173,068. Holography. WESTERN ELECTRIC CO. Inc. March 16, 1967 [March 29, 1966], No.12375/67. Heading G2C. Apparatus for successively recording holograms of different objects 42, 43 on the same photosensitive medium comprises a photo-sensitive medium 38, an element 37 exhibiting the electrooptic Kerr effect, a laser 35 providing a reference beam 36, lasers 40, 41 for projecting information carrying beams against the medium 38, each at a different angle, and means for selectively changing the index of refraction of the element 37 so as to change the direction of impingement of the reference beam on the medium 38. The index of refraction may be changed either by applying a variable electrical voltage to the element Fig. 3 (not shown) or by establishing a variable electrical voltage standing wave pattern in the element 37 to produce a selected variation in the refractive index along the length of the element. Apparatus for selectively retrieving information from a hologram comprises a laser 35 for projecting a coherent light beam along a path to the hologram, the element 37 lying in this path, and the means for selectively changing the refractive index being used so as to select the inclination of this beam to, and hence the information retrieved from, the hologram. The retrieved information may be projected on a screen 53. The recording and retrieving apparatus may be used to store telephone numbers, in which case a photo-detector array, a vidicon, or some other photo-sensitive medium may be used for detecting the information retrieved, converting it to electrical signals, and transmitting them to appropriate switching apparatus. In another embodiment Fig.1 (not shown) the location of impingement of the reconstructed image on a given plane may constitute information.

Abstract: 234,141. Russell, J. M. May 19, 1924,. [Convention date]. Parachutes.-The canopy of a parachute, stated to be positive in opening in spite of any twisting of the shrouds, is composed of a number of concentric sections having overlapping portions joined together at spaced points to provide a valve between them. In the construction shown, the canopy comprises two portions 12, 13 having an overlapping part 14 and secured together along the radial lines formed by the joint between the panels, which are reinforced by cords 17 preferably constituted by extensions of the shrouds 11. A cap portion 18 covering an opening in the peak of the canopy, is composed of panels 19 which overlap the panels of the upper section 12, to which they are secured along radial lines : they are fastened preferably to the upper ends of the cords 17. The edges of the panels 19 are wider than the panels of the section 12 where they overlap, and are stiffened by strips of webbing in order that directly the parachute is released they stand out and catch the upward draft, which enters the parachute and causes it to assume a pear shape. At this time the pressure within the parachute is less than the external pressure, the valves between the upper and lower sections 12, 13 are open, and the air admitted thereby fully opens the parachute. In this condition the internal pressure exceeds the external pressure and the overlapping portions of the sections 12, 13 are held tightly together. The parachute is preferably used in conjunction with a pilot parachute.

Title: Signalling devices employing mercury vapour lamps
IPC: H02M1/04
Filed: 1925-05-23
Abstract: 234,808. Toulon, P. M. G., and Soc. de Recherches et de Perfectionnements. Industriels. May 27, 1924, [Convention date]. Addition to 209,426, [Class 30 (i), Electric lamps, Arc &c.]. Optical apparatus. - The parent Specification and Specification 209,096, [Class 39 (i), Electric lamps, Arc &c.], describe a mercury vapour lamp in which ionization is kept up by a continuouslyapplied potential difference between mercury electrodes 5, 6 and the current between the electrodes 5, 3 is controlled by varying the potential of an exterior electrode 12.. According to the present invention, the variations in the luminosity of the mercury lamp may be employed, inter alia, for transmitting speech in a photophone system, a photographic sound record being produced at the receiving station. In the arrangement shown in Fig. 3, the intensity of the light beam 40 fluctuates in accordance with speech currents through the microphone 24, a screen 39 being employed if desired to cut out the visible spectrum. At the receiving station the light-fluctuations are translated into sound by a photo-electric cell, or are photographically recorded. Alternating current of fairly high frequency is supplied at 31 so that through the transformer secondary 32<1> an alternating voltage is applied between the electrodes 3, 5. Another secondary 32<11> is arranged in the plate circuit of a valve 27 together with a choke coil 36<1> which causes the plate current to lag by nearly 90‹ behind the voltage applied to the electrode 3. A further secondary 32<111> supplies current to a resistance 37, this current being substantially in phase with the applied E.M.F. The resistances 37, 30 are connected in series between the cathode 5 and control electrode 12, so that the voltage applied to the latter is the vector sum of the voltage drops in the resistances 37, 30. Hence the voltage of the electrode 12 differs in phase from that of the electrode 3 by an amount depending on the relative strengths of the currents in the resistances 37, 30 since these differ from one another in phase by about 90‹. Thus the microphone 24, which controls the strength of the component in 30. thereby controls the phase in 12, and so varies the luminosity of the lamp. The variations in luminosity may be recorded photographically so as to produce a sound record.
